BACKGROUND

1. Field of the Disclosure

The present disclosure relates to mass calling applications. More particularly, the present disclosure relates to utilization of a voice over internet protocol platform servicing mass calling applications.

2. Background Information

In a mass calling system, call processing commences with a caller at a public switched telephone network location dialing a telephone number. A local exchange carrier queries a database to determine which telecommunications carrier should handle the call. The database returns a carrier identification code and a routing number. In some cases, the routing number is a dialed toll-free number. In these cases, the local exchange carrier routes the call to a switch. The switch provides telephone messages to thousands of callers that access the switch. For example, a mass calling application for which a switch may be employed includes a tele-voting application.

Operations administration and maintenance tools are used to monitor, detect, and diagnose issues with voice over internet protocol ports. The operations administration and maintenance tools run on a data collections gateway. In order to remove mass calling applications from traditional and unsupported switching devices, mass calling applications are handled by a voice over internet protocol platform. When a server in the voice over internet protocol platform becomes inoperative, callers experience an impact to their calls. Accordingly, operations administration and maintenance tools allow an administrator to determine a utilization of voice over internet protocol ports in the voice over internet protocol platform.

Legacy long-distance services are replicated in a voice over internet protocol platform environment by supporting the de-loading of switches and edge switches. Accordingly, a replacement solution for the toll-improved service announcements and information collection (ISAIC) platform is provided. The ISAIC platform is a component of a time division multiplex network and supports interactive voice response functionality for playing announcements and collecting input from callers. These capabilities are used to support customers of various legacy long-distance services, including, but not limited to: positive call processing, a software defined network, an AT&T network connection, toll-free services, and custom mass calling event applications. The ISAIC platform also provides announcement provisioning and management capabilities. These announcement provisioning and management capabilities enable the advanced features services center to provision and manage announcements and ancillary data associated with the announcements (e.g. announcement text, announcement identifier) on behalf of long-distance customers. Announcement provisioning capabilities also enable customers to call an “8yy” number to record announcements in real-time. The ISAIC platform is transparent to long-distance customers.

In FIG. 2, voice over internet protocol platform 200 receives calls from a number of callers 202 a, 202 b, 202 c, 202 d, 202 e, 202 f at load-balanced sites 204, 206 at geographically distributed locations. Each of the load-balanced sites 204, 206 has a number of servers 208, 210, 212, 214, 216 and 218 that receive calls over the Internet at an application layer port. Caller 202 a and caller 202 b are each serviced by server 208 at load-balanced site 204. Caller 202 c is serviced by server 210 at load-balanced site 204. Caller 202 d is serviced by server 212 at load-balanced site 204. Caller 202 e and caller 202 f are serviced by server 216 at load-balanced site 206. Each received call is handled by a single voice over internet protocol port established by a server processing the call. A utilization tool at gateway servers 220, 222 obtain a metrics file from each server 208, 210, 212, 214, 216 and 218 at predetermined intervals. Alternatively, data from a metrics file for a particular server is transferred to the gateway servers 220, 222 when an alarm is generated. For example, the utilization tool may display utilization for a particular server when an alarm is generated that indicates that over 70% of the voice over internet protocol ports are being utilized on the server. In one embodiment, an alarm is customizable by a client application. Metrics files obtained by gateway servers 220, 222 are parsed by the utilization tool. In an exemplary embodiment, the utilization tool displays the obtained information at a device 224 separate from the gateway servers 220, 222.

A port may be a logical communication channel enabling communication between devices in at least one network. A recipient end point of the communication channel determines which application is to receive the data transmitted by a transmitting endpoint by using a port number contained in a received data packet. Ports are numbered 0 to 65535. Ports numbered 0 to 1023 are termed well-known ports as each port is reserved for known services such as file transfer protocol (e.g., port 21), simple mail transfer protocol (e.g., port 25), hypertext transfer protocol (e.g., port 80), and post office protocol 3 (e.g., port 110). Ports numbered 1024 to 49151 are termed registered ports, meaning they are registered for services, and ports numbered 49152 to 65536 are termed dynamic or private ports, which are used as required. A voice over internet protocol port or a voice port is a port by which voice over internet protocol application data (e.g., a voice call or speech signals) are received by a server in the voice over internet protocol platform. A port may also be a hardware interface by which a device is connected to other devices. More particularly, a port may be an outlet on a device to which a plug, electrical connector, or cable is connected. A signal or signals may be transferred from the device via the port to the connected connector.

In FIG. 3, at step S300, a voice over internet protocol platform receives a call at a site and a specified server and over a specified voice over internet protocol port. In step S302, the server processes the call according to the requirements for a client application with which the call is associated. For example, a tele-voting application may require that a server play three prerecorded messages and obtain a selection from the caller. The same server may also service calls for a customer service center, which may require the server to obtain a client identification number from the caller and retrieve a client file associated with the client identification number. The server creates a call log entry regarding the disposition of the processed call in step S304 and stores the call log entry in a call log, or metrics file on the server. The utilization tool obtains real-time updates from a call log for each server processing calls at a site in step S306. In step S308, server utilization at each load-balanced site is displayed. In one embodiment, server utilization is displayed based on each client application originating calls. That is, utilization per server is displayed by the client application requiring call processing operations to be performed by the server. In another embodiment, the display is a graphical user interface. In step S310 the utilization tool sends a notification to an operations site regarding impending issues.

The utilization tool displays, to a device able to access the gateway servers 220, 222, or a device able to receive display data from the gateway servers 220, 222, the number of voice over internet protocol ports being used by each server 208, 210, 212, 214, 216 and 218. The utilization tool updates a display of a number of voice over internet protocol ports being used at each server and each load-balanced site. The utilization tool dynamically updates the display of voice over internet protocol port utilization in real-time. As shown in FIG. 4A, voice over internet protocol port utilization data includes available ports, used ports, and percent usage by server, group and site. In one embodiment, the voice over internet protocol port utilization tool has automatic update capability with a one minute refresh frequency.

In FIG. 4B, voice over internet protocol port utilization is shown for each server in the voice over internet protocol platform, as utilized by each client application. That is, the number of voice ports allocated to each client application, the number of allocated voice ports in use by the server to process calls associated with each client application, and the percentage of voice ports in use by each client application, is shown.

Accordingly, the present invention enables a user to monitor the utilization of voice over internet protocol ports by receiving calls via voice ports established by servers, aggregating utilization information for each of the servers in accordance with applications associated with the calls, and separately displaying the aggregated utilization information for each of the applications, each of the applications corresponding to a distinct subset of the calls.

Although the invention has been described with reference to several exemplary embodiments, it is understood that the words that have been used are words of description and illustration, rather than words of limitation. Changes may be made within the purview of the appended claims, as presently stated and as amended, without departing from the scope and spirit of the invention in its aspects. Although the invention has been described with reference to particular means, materials and embodiments, the invention is not intended to be limited to the particulars disclosed; rather the invention extends to all functionally equivalent structures, methods, and uses such as are within the scope of the appended claims.

For example, the utilization information displayed is used by a user to reconfigure the load-balancing of servers, groups or sites. In this example, the user is an operations administrator. If the utilization of a server is over 45%, as an example, calls will no longer be routed to the server. Rather, another server having a lower utilization, another group having a lower utilization, or another site having a lower utilization will receive the call. As shown in FIG. 4A, server 6 and server 7 located in group A of site 2, server 8 and server 9 located in group B of site 3 each have a utilization that is over the predetermined 45% threshold. An operations administrator may subsequently reconfigure load-balancing by routing traffic for sites 2 and 3 to site 1. Alternatively, traffic directed for servers 8 and 9 in group A may be redirected to server 10 in group B at site 3. As another alternative, traffic destined for server 6 in group A of site 2 may be rerouted to server 7. A load-balancing configuration may be reconfigured based on any configuration or grouping of servers in a voice over internet protocol platform. In addition, a group may be any grouping of servers at any number of sites based on a number of criteria chosen by an operations administrator or a system architect.

In another embodiment, the display is accessible by a user of the voice over internet protocol platform. In this example, the user is a caller using a mass calling application service. The caller may access the display and make calling decisions based on utilization information for the voice over internet protocol platform. For example, if the utilization of the voice over internet protocol platform is relatively low, then a caller may infer that a significant number of callers are not calling in to vote in a tele-voting application and may decide to place a call.

In yet another embodiment, a user may be the business department of a client application serviced by the voice over internet protocol platform. The user may use the display to determine whether another client application is monopolizing server or voice over internet protocol platform resources. The user may change business agreements based on the display of utilization information.

In still another embodiment, the display is a graphical user interface that is enabled to filter data to display requested items. A user of the display may enter input into a dialog box, drop-down menu, or other implementation of a selection tool selection criteria. For example, the user enters selection criteria including, but not limited to: servers having more than one thousand ports, all servers located at site 1, servers for which the utilization is over 40%, servers located at a specified geographic location, and servers for which over 500 ports are in use. It is noted that the selection criteria includes any information about the voice over internet protocol platform that is stored. One or more selection criteria may be entered by the user.

The term “computer-readable medium” shall also include any medium that is capable of storing, encoding or carrying a set of instructions for execution by a processor or that cause a computer system to perform any one or more of the methods or operations disclosed herein.

In a particular non-limiting, exemplary embodiment, the computer-readable medium can include a solid-state memory such as a memory card or other package that houses one or more non-volatile read-only memories. Further, the computer-readable medium can be a random access memory or other volatile re-writable memory.
